Final answer:
To multiply the given expressions, simplify the coefficients and add the exponents of the variables with the same base.
Step-by-step explanation:
To multiply the given expressions, we can use the rules of exponents and the distributive property.
First, we can simplify the coefficients: 2 * 6 = 12.
Then, we can multiply the variables with the same base by adding their exponents: v * v² = v³ and y⁴ * y³ = y⁷.
Combining the simplified coefficients and variables, the final answer is 12v³y⁷.
